"How to cook spent at home?"

Step 1: Gather the necessary ingredients
Concentrated nitric acid;
Concentrated sulfuric acid;
Concentrated Potassium nitrite;
Concentrated cellulose ether;
Distilled water;
Measuring cup;
Large glass container;
Plastic container;
Safety glasses and rubber gloves.
Step 2: A mixture of nitric and sulfuric acids

Mix 250 ml of concentrated sulfuric acid with 100 ml of concentrated nitric acid in a large glass container for chemical experiments. This mixture should be gently stirred until it becomes homogeneous.

Step 3: Add Potassium Nitrite
Slowly add 40 grams of potassium nitrite and stir gently until it completely dissolves. This reaction will increase the temperature of the solution, so it is necessary to carefully keep it under control.

Step 4: Add Cellulose Ether
Add 50 grams of cellulose ether and mix gently until this component is completely dissolved. This addition will create a thick liquid.

Step 5: Dilute the mixture with water
Add 500 ml of distilled water and continue stirring the mixture. It is necessary to carefully keep it under control, since the formation of gases can lead to a sharp increase in temperature.

Step 6: Move the spent into a plastic container
When the mixture is fully formed, it can be transferred to a plastic container. It must be tightly closed so that there is no possibility for air to go inside.

Note: When working with waste, all safety measures must be observed. Spending is very dangerous and can lead to life-threatening consequences.
